Bushcraft maintenance: 5 maintenance steps at the beginning of spring

Step 1: Re-waterproof the textiles

This is the point most people overlook. A Gore-Tex jacket doesn't lose its internal waterproofing, but it does lose its DWR (Durable Water Repellency), the surface treatment that makes water bead up. When the DWR wears off, the outer fabric becomes saturated and heavy, and even if the inside remains dry, thermal insulation drops drastically. The telltale sign: water no longer beads up; it spreads out in a dark stain.

The procedure: First, wash with a technical detergent (Nikwax Tech Wash, Grangers, for example), never use regular detergent which clogs the pores of the membrane. Apply the DWR treatment by spraying it onto the dry fabric or by soaking it in the washing machine. Finish by tumble drying on low heat or steam ironing: the heat reactivates the DWR molecules. The same treatment applies to your tarp: waterproofing spray + seam control (Seam Grip if a seam is leaking).

Step 2: Sharpen the knife and the axe

A sharp tool is a safe tool. A dull tool forces, slips, causes fatigue, and can lead to injury. Check the edge condition with the thumb test (you can feel the micro-serrations without touching the cutting edge) or the paper test (a sharp blade cuts cleanly, a dull blade tears).

For the knife: use a medium-grit stone (400-600 grit) if the edge is damaged, then a fine-grit stone (1000-2000 grit). Maintain a constant angle of 15 to 20 degrees. Finish on a leather strop with honing paste. For the axe: use a wider angle (25-30°), a flat file for the notches, and finish on a fine stone.

Step 3: Inspect the ropes

Paracord, Dyneema, tarp bungee cords: all of them degrade under the combined effects of UV rays, humidity, and repeated knotting. Uncoil each cord completely and run it between your fingers. Look for stiff or discolored areas (UV), frayed sections, and internal hard spots (partial fiber breaks). A cord that looks suspect cannot be repaired; it must be replaced. Paracord costs less than one euro per meter.

Also check your tarp tent pegs: a bent peg won't stay in the soft spring soil. Straighten any slightly deformed ones, and discard any broken ones.

Step 4: Clean the stove

The gas stove accumulates combustion deposits in the burner and jets. A dirty stove is difficult to start, consumes more fuel, and produces an uneven flame. Disassemble the burner. Clean the jet with a fine needle (never use a wooden toothpick, which leaves fibers!). Check the valve's O-ring: if it's cracked or hard, replace it before a leak occurs while camping. Test the ignition outdoors before packing away.

For alcohol or wood stoves: clean black deposits with damp baking soda and check for thermal deformation.

Step 5: A complete tour of the bag

Five non-negotiable points:

• Sleeping bag : remove it from its compression bag and let it reinflate for 24 hours. A down sleeping bag that does not regain its original loft (i.e., the ability of its filling to inflate) has lost its insulation; a specific down wash is required (Nikwax Down Wash).
• Shoes : check the wear on the Vibram sole, the side seams, and the condition of the tongue. Condition the leather if necessary and waterproof it, regardless of the material.
• First aid kit : expiry dates of medications, condition of packaging, replacement of what was used in winter.
• Headlamp : Remove the batteries if you are not going out for two weeks, as they leak and corrode the contacts. Test the maximum intensity.
• Ignition : lighter gas level, ferrocerium to be replaced if the stick is two-thirds worn.

Well-maintained equipment is equipment that gets forgotten.

A knife that cuts, a jacket that waterproofs, a stove that starts at the first click: this is the kind of gear you no longer need to worry about in the field. That's precisely the point. The best equipment is the kind that fades into the background because it does its job. This March maintenance check buys you months of worry-free outings.
